We investigated the influences of positive thought about social capital on social participation of the elderly Koreans. The study design was cross-sectional analysis of the National Statistic Office Study of Korean Society Statistics Survey 2003. Participants were total of 8,586 representative samples. Two types of social participation were investigated: meeting attendance and volunteer obligations. The base model included five thoughts about social capital that must be settled as a priority in Korea, i.e., reducing the differences between the rich and the poor, reducing the crime rate, reducing regulations and corruption, improving the moral level, eliminating environmental pollution. Social participation was influenced by positive thoughts about social capital, and different kinds of thoughts had different influences on different types of social participation. The elderly who responded positively to 'reducing the differences between the rich and the poor' attended all two types of social participation more. Along with education and health status, positive thought about social capital is another important factor that influences increased social participation. It may also compensate for deteriorating health with increasing age by promoting social participation. Encouraging social participation is a good way to improve the health of the elderly, as are efforts to change thought about social capital positively.

Low birth rates and aging problems are raising a big issue in the worldwide. Recently, Korea also has no one to caring children who have low discernment and old ones who have Alzheimer's disease because of growing nuclear families and dual income furnitures. Therefore many serious crimes like kidnappings were occurred by people who have mental problems or bad intentions. Even though missing and ding alone are increasing together. The result of it, the needs of potable GPS system, to tracking for the olds and week ones, is highly growing nowadays. This paper introduce producing prototype tracker, looks like fashion accessories, which is using GPS, Zigbee and WiFi. It expects developing many accessory types of trackers effectively helps protect children and old ones from kidnappers at a low cost in this aging society.

Serial violent crimes have occurred more frequently. Additional attention is paid to relevant areas in which discussions has also increased. This study analyzed Young-cheol Yoo, serial killer case. Two of Yoo's crimes were studied for modus operandi. The cases selected were the premeditated break-in homicide of upper-class elderly people and the impulsive homicide of the Hwanghak-Dong street vendor. Crime motives, targets, times, places, means and methods were analyzed. Profiling techniques in Young-cheol Yoo cases were evaluated and the problems discovered during investigation were discussed. The followings are the findings of the analysis of the serial killer Yoo cases. Yoo exhibited a hatred toward the rich, the elderly, and women as well as a fear of diseases and death. Yoo's crime targets were the elderly residing in wealthy houses, street vendors and prostitutes. The numbers of victims were: 3 men and 5 women victims in 4 homicide cases involving the elderly residents in wealthy houses; one man in 1 street vendor homicide case 11 women in 11 prostitute homicide cases, so total 20 persons were murdered in 16 cases. The time of the crimes were between 10 am and noon in the homicide cases of the elderly and very late at night or early in the morning in the prostitute homicide cases. Means and methods facilitated include the use of a knife as a threat and a hammer made by Yoo to strike the head and face of victims. In the homicide cases involving the elderly, he attempted to disguise the crime scene as a burglary or committed arson to destroy the evidence; in the prostitute homicide cases, bodies were mutilated and buried in secret. 1) Generally each serial killer case has different characteristics, motives, and purposes; while some serial killer cases involve similar methods, others use different methods. Unlike other crimes, serial killers' characteristics and tastes are very different, so it is difficult to explain serial killings based on a specific model. It is important to accurately capture modus operandi of each serial killing and for detectives to familiarize themselves with them. The process of tracing and use of imagination which follows a serial killer's psychology and thought must be used to find out what kind of thoughts pushed the killer to commit the crime. In order to investigate and research difficult subjects such as serial killing, various methods, skills, and relevant knowledge should be studied, and institutional endeavors should go hand in hand with individual efforts.

As the number of single-person households is increasing in Korea, the demand for emergency support networks for the elderly and women is also growing. To meet the need, systemic solutions, such as a wide distribution of cell phones with embedded motion sensors that can alert the first responders or police in case of health or safety crisis, are regarded as critical issues. This paper introduces a design which registers the user's motions to process emergency reports via a mobile app running in the background. The method offers an affordable solution to reporting emergencies taking place both indoors and outdoors as it does not require an addition of hardware but only simple hand gestures.

This treatise made a general survey of the welfare policy in our country, and examined the present condition of welfare facilities and distributional trait in Taegu, setting the limits of welfare to welfare facilities. As the result, I could get conclusion like this. First, the present condition of welfare facilities in Taegu exceeds the national average value. Second, the distribution of housing facilities generally corresponds with the distributional area of low-income class and has an unbalanced distributional trait. Third, public facilities are distributed in periphery of the city and we can see they are regarded as loathsome facilities. Lastly, most of the welfare facilities except welfare house are small-scale and worn-out and also petty because they are run by individuals. With basis on this result of the research. I want to make these suggestions. That is, the improvement in quality than in quantity must be made. In addition, until now welfare facilities have restricted users, but from now on they must be converted to public services for most of a nation. To realize those things, welfare facilities must be located in the site where traffic is convenient and medical facilities are neighboring. In conclusion, the socialization of welfare facilities must be carried out.

The missing child problem is no more a personal problem. It became a social problem that all parents must consider. To this, this study applies USN/RFID technology integrated with GIS for the prevention of missing child. Although RFID is not designed for location sensing, but now it is regarded as a device to facilitate real time location awareness. Such advantages of RFID can be integrated with 4S(GIS/GPS/LBS/GNSS) achieving much synergy effects. In order to prevent kidnapping and missing child, it is necessary to provide a missing child preventing system using a ubiquitous computing system. Therefore, the missing child preventing system has been developed using high-tech such as RFID, GPS network, CCTV, and mobile communication. The effectiveness of the missing child prevention system can be improved through an accurate location tracking technology. This study propose and test a location sensing system using the active RFID tags. This study verifies technical applied service, and presents a system configuration model. Finally, this paper confirms missing child prevention system utilization possibility.

This study is to examine the impact of spatial characteristics of cities on homicide based on spatial econometric model. It selects housing types, racial heterogeneity, residential instability, overcrowding, commercial area, rate of 15 to 29 ages, and rate of the elderly as variables for spatial characteristics of cities. This study employs spatial regression analysis applying the spatial error model to analyze the data from 229 locals collected from Korean Statistical Information Service and Statistical Year Book of local governments. As a result, it shows that homicide has close relationships with apartment and multi-housing as housing types, racial heterogeneity, residential instability, and overcrowding, but not with the commercial area, rate of 15 to 29 ages, and rate of the elderly. The study contributes to expanding understanding and explanation on the causes of homicide focusing on social-structure approach for criminology by analyzing a more advanced model in applying variables than one of existing literature. This study suggests follow-up research on homicide based on both social-behavior approach and social-structure approach in the near future for the development of criminological theory.

Korean society in the 2000 has experienced new many social and spatial issues such as the process of neoliberalism and changes in urban and spatial policies, the development of information and communication technology and reconfiguration of informational social space, radically increasing foreign immigrants and transformation to multicultural society, global warming and environmental injustice, and these new issues have promoted development of social geography in Korea. In addition to a review on them, this paper provides a review on empirical researches on traditional issues which have been dealt with in social geography in the 2000 in Korea. Even though there have been numerous sub-issues, they can be divided into two categories: one is urban and communal social geography including urban housing and residential segregation, urban social problems such as poverty, crime, education, health care, social welfare, urban and rural community building, identity, sense of place, and social movement; the other is social geography of population and migration, including population movement, aged society and social welfare for elderly people, and foreign immigrants and formation of multicultural social space. As some difficult conditions such as path-dependent process of neoliberalism, transformation toward informational, aged, and multicultural society would continue, so social geography in Korea to tackle with these external conditions should deepen its theoretical insights and widen its research issues.

A new urban paradigm that moves from a vehicle-centric to pedestrian-centric culture should be considered to improve the quality of the pedestrian environments for women, children, senior citizens, and disabled persons as well as to promote community unification by providing general movement rights to everyone. This study was implemented to provide decent alternatives to improve street spaces. The street spaces around the Commercial and Residential Area No.1 located in the Administrative-Centered City, Sejong Special Autonomic City, were selected to analyze and define the status of the walkways and the street spaces. Satellite imagery and numerical maps were used to collect geographic data. Practical and actual surveys for the selected sites were performed to analyze the street status and the pedestrian status. Based on the all collected data, analysis results, and literature reviews, the questionnaire was made, and 315 inquiries qualified for analysis. The physical status of all four study sites was the highest level, Grade A, and green open spaces were relatively sufficient. As a result, the factors obtained from the factor analysis have an impact on the satisfaction of the pedestrian streets in the commercial area. The factors are as followed Design > Convenience > Roadside trees and rest areas > Safety > Safety protective facilities > Transportation and information facilities > Continuity > Basic state of road surfaces > Comfortability, and in the residential area: Transportation and information facilities > Basic state of road surfaces > Comfort > Convenience > Continuity > Design > Illumination and crime prevention facilities > Safety > Roadside trees and rest areas.

Hate is a collective expression of exclusivity toward others and it is fostered and reproduced through false public perception. This study aims to explore the objects and issues of hate discussed in our society using text mining techniques. To this end, we collected 17,867 news data published from 1990 to 2020 and constructed a co-word network and cluster analysis. In order to derive an explicit co-word network highly related to hate, we carried out sentence split and extracted a total of 52,520 sentences containing the words 'hate', 'prejudice' and 'discrimination' in the preprocessing phase. As a result of analyzing the frequency of words in the collected news data, the subjects that appeared most frequently in relation to hate in our society were women, race, and sexual minorities, and the related issues were related laws and crimes. As a result of cluster analysis based on the co-word network, we found a total of six hate-related clusters. The largest cluster was 'genderphobic', accounting for 41.4% of the total, followed by 'sexual minority hatred' at 28.7%, 'racial hatred' at 15.1%, 'selective hatred' at 8.5%, 'political hatred' accounted for 5.7% and 'environmental hatred' accounted for 0.3%. In the discussion, we comprehensively extracted all specific hate target names from the collected news data, which were not specifically revealed as a result of the cluster analysis.
